This is a neat little instructable. for one thing, you do not need a pot of grease or oild to form taco shells the way you want. Just throw them in the oven as I describe and you have a healthier taco shellls!

Step 1: What's needed.
Oil to baste the tortillas
Cheap two for a dollar cookie sheets.
Scissors or a knife.
Step 2: Prepping the oven stands
#1 Take one cookie sheet and fold it in half longways. then fold the long edges to make a base.
#2 Take the cookie sheet two so that it has a canal in the center. probably no wider than an inch.
It make seem like the tortillas do not wrap around right, but when they heat up, they will relax and fit to the form.
Step 3: Baking the shells.
Note: Be sure to use oven mitts or heat proof pads to remove the shells from the oven as they will be very HOT!!!
Step 4: Tortilla chips and tostada bases
Step 5: Make some tacos.
Note: Sorry for some of the pictures. Steam rising clouded the lens. I did not realise it until the instructable set up was already done.
